Invitae RCV000809242 SCV000949385 uncertain significance Neuroblastoma, susceptibility to, 3 2023-11-29 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Asp1203Argfs*82) in the ALK gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in ALK cause disease. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with ALK-related conditions. ClinVar contains an entry for this variant (Variation ID: 653463). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV001020702 SCV001182215 uncertain significance Hereditary cancer-predisposing syndrome 2022-03-03 criteria provided, single submitter clinical testing The c.3605dupG variant, located in coding exon 23 of the ALK gene, results from a duplication of G at nucleotide position 3605, causing a translational frameshift with a predicted alternate stop codon (p.D1203Rfs*82). This alteration is expected to result in premature protein truncation or nonsense-mediated mRNA decay. However, loss of function of ALK has not been clearly established as a mechanism of disease. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
